SPECIFICATION forming part of Letters Patent No. 287,632, dated Octoberso, 1883; Application filed Auteur-1583. (No model.)

' To on whom it may concern:

Be it known that 1, CHARLES BARCLAY COOPER, of Nashville, in'the countyof Davidson and State of Tennessee, have invented a new and usefulImprovement in Sheet-Metal Roof-Valleys, of which the-following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in IO which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of myimprovement, shown as applied to a roof.Fig. 2 is a longitudinal section of my improvement, taken I 5 throughthe line w m, Fig. 1. Fig. 3 is acrosssection of the same, enlarged,taken through per corners, whereby the overflow of water will beprevented, the shingles will be keptout of contact with the uppersurfaces of the sections, and thesections can be readily secured to theroof-boards and to each other, as

3 5 will be hereinafter fully described.

A represents the roof-boards, which meet at an angle andform avalley orgutter, as shown in Figs.'1 and 3.

B are strips of -sheet metal bent longitudi- 0 nally'at such an anglethat they will fit into the angle of the roof-boards A, as shown in Fig.3. The sections B are laid with the lower end of each upper sectionoverlapping the upper end of the next lower section, as shown in Fig. 1.

To the upper corners of each section B are attached lugs O, whichprojectin such directions as to lie squarely upon the roof-boards A, and areperforated to receive the nails that secure them to the saidroof-boards. With this construction the sections B are fastened at theirThe invention consists in sheet-metal roof-- upper ends only, and arethus free toexpand and contract without affecting their position uponthe roof-boards. The upper end edge of each section is flanged or bentover upward 7 upon itself, forming an upwardly-projecting bead, D, andthe lower end edge of each section is flanged or bent over downward uponitself, forming a downwardly-projecting bead, E. The beads D E, when theadjacent ends of 6Q the sections B are overlapped,'will be at a littledistance apart,.1eaving an air-space between them, and preventing thewater passing down the valley from flowing over the upper edges of thelower sections, and thus getting access to the roof-boards. V

Along the side edges of the sections B are formed upwardly-projectingbeads F, upon which the shingles G, metal plates, or slates covering theroof, rest and receive afirm support. The beadsF also prevent the waterfrom flowing over the side edges of the sections B beneath the shinglesG and wetting the roof boards A. Another advantage of the beads F isthat they prevent the parts of the shingles 7 5 that overlap the sideparts of the sections B from resting upon a flat surface, and thusretaining moisture, and causing it to pass over the edges of the saidsections B by capillary attraction.

If desired, branch beads H may be formed extending inward from the beadsF, and bent downward toward the lower ends of the sections B, as shownin Figs. 2, 4, and 5, to offer an additional safeguard against thepassage of 8 5 water over the side edges of the said sections B. Thefree lower end of each upper section, B, is held down upon the upper endof the next lower section by lugs I, attached to the upper corners ofeach section, and which are 0 bent down over the side edges of the lowerends of the upper section, as shown in Figs. 2. and 3, so that the saidlower ends will be held securely in place.

' Having thus described my invention, I claim 5 as new and desire tosecure by Letters Patent- 1. Sheet-metal roof-valleys made in sections,substantially as herein shown and described, with upwardly-projectingbeads along their side'and upper endedges, a downwardly-pro- Ioo jectingbead at their lower end edge, and pairs of lugs at their upper corners,as set forth.

2. In sheet-metal roof-valleys, the upwardlyprojecting beads F, formedalong the side edges of the valley-sections B, substantially as hereinshown and described. whereby the shingles will 5 be supported and theoverflow of water will be prevented, as set forth.

3. In sheet-metal roof-valleys, the beads D E, formed upon the ends ofthe sections B, substantially as herein shown and described, to

10 prevent water from flowing back between the overlapped ends of thesections, as set forth.

4. In sheet-metal roof-valleys, the upwardly-projecting branch beads H,formed in the
